Summary
Submitted by aeeben on 31 March 2018
Interlaced 80 columns routine in 125 bytes of code. A silly side step from the 128-byte font compo.

Kernal editor only writes to even columns. To use the odd columns, you must write directly to a second screen matrix, starting at $2000 (8192).

Examples (copy/paste to x64):

fora=0to127:poke1824+a,a*2:poke8992+a,a*2+1:next (writes all 256 characters at bottom of screen)

fora=0to199:poke1624+a,peek(1024+a*2):poke8792+a,peek(1025+a*2):next (copies top 400 characters from standard screen to lower half of screen using both even and odd columns)

fora=0to999:poke1024+a,(a*2)and255:poke8192+a,(1+a*2)and255:next (fills the screen repeating all 256 characters)

fora=0to999:poke8192+a,32:next (clear the odd columns)
